DVT / Test Validation Engineer | 9+ Years in Reliability & Environmental Testing | Building SW QA & Test Automation
I currently work in industrial computer DVT / test validation, with more than nine years of experience in reliability, environmental testing, and validation workflows.
I am extending this background into software QA and test automation through personal projects. My engineering approach emphasizes testability, traceability, workflow correctness, and evidence-based decisions.
I use AI coding agents to accelerate implementation while remaining responsible for requirements, risk assessment, review, testing, and final technical decisions.

DVT／測試驗證工程師｜9 年以上可靠度與環境測試經驗｜持續建立 SW QA／測試自動化能力
現職從事工業電腦 DVT／測試驗證，具備 9 年以上可靠度、環境測試與驗證流程經驗。
目前透過個人專案，將既有驗證背景延伸到 SW QA 與測試自動化。我的工程思維重視可測試性、可追溯性、流程正確性，以及能以證據支持的技術判斷。
我會使用 AI coding agent 加速實作，但需求定義、風險判斷、程式審查、測試驗收與最終技術決策仍由我負責。
